二分. 首先把字符串处理成一个数组,二分答案,判断一下即可. #include <cstdio> #include <cmath> #include <set> #include <cstring> #include <algorithm> using namespace std; int p; int a[1000010],sz; char s[1000010]; void work() { int sum=0; for(int i=0;s[i…

codeforces.com/contest/803/problem/D [题意] 给定一个字符串,字符串里可能有空格和连字符‘-’,空格和连字符的意义是一样的,都表示:能在那个位置把字符串分成两部分,且两部分分到两行去,空格或连字符留在当前行. 这个分裂操作能够使得原字符串不断变短; 问你最后获得的所有字符串(可能分裂成了多行,所以是”所有”)中最长的那个最短能够是多少: 分裂操作最多只能操作k次: [思路] 这种题已经做过多次了,要找最长的那个最短的,直接二分查找最短值,每次贪心划分,看总行…

[题目链接]:http://codeforces.com/contest/803/problem/D [题意] 给你一个字符串; 其中的空格和连字符表示可以折叠的部分 (就是说能在那个位置把字符串分成两部分,且和两部分分到两行去); 这个操作能够使得原字符串不断变小; 问你最后获得的所有字符串(可能分裂成了多个,所以是"所有")中最长的那个最短能够是多少; (这个操作最多只能操作k次) [题解] 二分答案; 枚举最后那个最长的长度是多少x; 现在,相当于让你最多切k-1刀; 使得k个部…
